Maduru Oya National Park (MONP) (588 km2) lies in the districts of Ampara and Polonnaruwa representing areas of the dry zone. The climax plant community of the area is tropical dry mixed evergreen forests. However, large tracts of forests within the park had been severely exploited for shifting cultivation resulting in secondary forests and vast st...
Human-elephant conflict (HEC) is a major problem to Tissmaharama Divisional Secretariat (TDS) in Hambantota District, Sri Lanka. The current study was designed to identify and describe the patterns of HEC in TDS so that methods could be developed to minimise human and elephant deaths due to HEC. The data were collected through questionnaire surveys...
There are 2 species of slender lorises found in Sri Lanka: the red slender loris, Loris tardigradus (Linnaeus, 1758), endemic
to the wet zone and montane areas, and the grey slender loris, Loris lydekkerianus (Cabrera, 1908), which is widespread. In addition,
currently there are 2 subspecies recognized for each of these 2 slender loris species of S...
Habitat relations of the Asian elephant (Elephas maximus maximus) were studied in Maduru Oya National Park (MONP) located in the dry zone of Sri Lanka with objectives of understanding the temporal and spatial distribution of elephants in different habitats, social structure, and food habits. Six different habitat types namely; grasslands, scrubland...
External body dimensions and proportions, skull morphology, coat coloration, vocalizations, and genetics have contributed to an increase in the number of diagnosable species among nocturnal primates. Two species of slender loris are currently recognized for Sri Lanka: the red slender loris Loris tardigradus (Linnaeus, 1758), endemic to the wet zone...
The Open University of Sri Lanka (OUSL), being the premier Open and Distance learning institution in the country, provides immense opportunity for students to carry out their studies through Open and Distance Learning (ODL) methodologies. Established in 1980, under the Universities Act, OUSL constitute of eight faculties and Institutions, of which...
The Red slender loris (Loris tardigradus) is an endangered and endemic primate species inhabiting the wet zone of Sri Lanka; a global biodiversity hotspot. The Zoological Society of London's EDGE of Existence programme ranked L. tardigradus within the top 100 of global mammal priority.And recently it has been listed as Sri Lanka's five most concern...
Geographic Information Systems and Remote sensing are treated as powerful
analysis and decision making tool used in a spectrum of applications in different fields. Montane
Slender Loris is endangered primate subspecies and found only in the Montane rainforest
region of Sri Lanka. This research study is an attempt to explore the application of habit...
The red slender loris (RSL) is an endangered endemic primate inhabiting the wet zone of Sri Lanka; a global biodiversity hotspot. The wet zone faces severe problems of habitat loss and fragmentation and just eight percent of its original forest cover now remains intact. This situation seriously undermines RSL’s long-term survival. Furthermore, info...
We report here the first close examination in 70 years of the Horton Plains slender loris, Loris tardigradus (lydekkerianus) nycticeboides, previously known only from two collected specimens and a number of sightings from eye-shine. Photographic and morphometric data presented here enable a preliminary assessment of the possible distinctive endomor...
Mixed-species bird flocks are attractive models for the investigation of geographical variation in animal communities, as they represent a subset of the avifauna in most forested regions of the world. Yet studies of the regional variation in flock size and the composition of flocks are few, due to the predominance of studies carried out at single s...
Social relationships of juvenile wild elephants (3-6 years old) in the Udawalawa National Park were studied. Focal animal sampling was employed to quantify behaviour of juveniles encountered on 450 different occasions. Nearest neighbour (NN) and nearest neighbour distance (NND) were considered for proximity analysis and the social relationships of...
Food habits of sika deer (Cervus nippon) on Kinkazan Island were studied to show (1) whether local variations exist on this small island (9.6 km2); (2) which kinds of plants are the staple foods for the deer living in the plant communities heavily affected by deer gazing; and (3) whether dietary differences exist or not among males, females, and fa...
2007: Home ranges and habitat use of sloth bears Melursus ursinus inornatus in Was-gomuwa National Park, Sri Lanka. -Wildl. Biol. 13: 272-284. We studied home ranges and habitat selection of 10 adult sloth bears Melursus ursinus inornatus at Wasgomuwa National Park, Sri Lanka during 2002-2003. Very little is known about the ecology and behaviour of...
The sambar Cervus unicolor has a large population in southern Asia. In Sri Lanka, its habitat use is most common among the four cervid species. We carried out an analysis of the food habits of sambar in the Horton Plains National Park from January to November 1991 by using the quantitative fecal analysis method. Analyses of sambar feces collected a...
Dietary differences in the ages and sexes of Sika deer (Cervus nippon) were studied on Kinkazan Island, northern Japan from October 1990 to July 1991. Larger deer consumed more graminoids than
smaller deer except in spring, and less dicotyledonous leaves in all the seasons. Fecal nitrogen concentrations were lower
in larger deer than in smaller dee...
Natural Plasmodium vivax malaria infections in man evoke anti-gamete transmission blocking antibodies which influence the infectivity of malaria patients
to the vector mosquito. In this study, entomological, immunological and parasitological data obtained through the monitoring
of an epidemic of human vivax malaria in Sri Lanka were used in a mathe...
